Abstract

The influence of different pressures, temperatures, scattering angles and incident wavelengths to the relative intensity of the Brillouin peaks to the Rayleigh peak and the Brillouin shift in the spontaneous Rayleigh-Brillouin scattering (SRBS) spectra of N₂ is analyzed by using the Tenti S6 model. A system for detecting the SRBS spectra of gas is also introduced in this paper. The SRBS spectra of N₂ at different pressures with the incident wavelength of 532nm, the temperature of 300K and the scattering angle of 90° have been measured, the experiment results are well agreed to the simulations.
